Heart Failure Study of Multi-site Pacing Effects on Ventriculoarterial Coupling

"Instead of administering a single LV pulse at the most (electrically) delayed segment of the ventricle, multi-site pacing allows for a more detailed sculpting of the LV activation sequence. Based on the MPP-IDE study results, activation of the antero-lateral wall, or at least its most delayed segments, closely followed by a pulse to the apex and then by a right ventricular one will yield favorable results in terms of hemodynamics and clinical parameters.~Programming features:~* Interpolar distance for the first left ventricular pulse \>30mm (i.e. non-sequential poles used)~* Nearly simultaneous (Δt=5msec) second left ventricular pulse and~* Threshold of ≤[email protected]"
